Product Description 718 die steel has the same use as P20 type die steel, but because of its better hardenability and superior performance, it can make large and high-grade plastic die forming parts. With the development of plastic moulds, there will be more and better updating of improved mould steel numbers. The B30H of Baosteel in China is an example.Thermoplastic injection mold, extrusion mold.Die steelDie steelThermoplastic blow moulds.Main parts of heavy-duty die.Cold structural parts.It is often used to make TV case, washing machine, refrigerator case, bucket and so on.Chemical Composition elementCSiMnMoCrNistandardContent (%)0.28~0.400.20~0.800.60~1.000.30~0.551.40~2.000.80~1.20YB/T127-1997Material Performance physical property(hardness 340HBW, at room temperature and high temperature)1) Temperature 20 C/200 C/400 C, density 7.8g/cm/7.75g/cm/7.7g/cm.2) Temperature 20-200 C/20-400 C, linear expansion coefficient: 12.6 10K/13.5 10K.3) Temperature 20 C/200 C/400 C, thermal conductivity 29.0W (m K) / 29.5W (m K) / 31.0W (m K)4) Temperature 20 C/200 C/400 C, modulus of elasticity: 205 000 MPa/200 000 MPa/185 000 MPamechanical property(hardness 340HBW)1) Temperature 20 C/200 C/400 C, tensile strength 1100 MPa/1050 MP8/850 MPa.2) Temperature 20 C/200 C/400 C, conditional yield strength 980 MPa/925 MPa/770 MPa.3) Temperature 20 C/200 C/400 C, section shrinkage 49%/51%/52%.4) Temperature 20 degree C/200 degree C/400 degree C, elongation 13%/14%/16%.5) Temperature 20 C/200 C/400 C, impact toughness (>) 20J/cm/32J/cm/42J/cmcritical temperaturecritical pointAc1Ac3Ar1Ar3MsMfTemperature (approximation) / TemperatureSeven hundred and seventyEight hundred and twenty-fiveSix hundred and fortySeven hundred and fifty-fiveThree hundred and thirty-fiveOne hundred and eightyCoefficient of expansionTemperature / C18~10018~20018~30018~40018~50018~60018~700Linear (Expansion) Expansion Coefficient/C11.9 x 1012.20 x 1012.50 x 1012.81 x 1013.11 x 1013.41 x 1013.71 x 10Company information:Bozhong Group Mainly supply in forms of coil, sheet, plate, rod, bar, tube, pipe, beam, angle, flange, wire, strip, channel, etc., with various varieties, wide range of dimensions, high purity, stable chemical composition, high dimensional accuracy and excellent surface quality.
